Subject: [PATCH v3 00/12] qrb4210-rb2: add wsa audio playback and capture
 support

Rebased, updated, re-tested. This implements the playback support via the
following path: RX1 from DSP is connected to rxmacro which communicates
with wcd codec using soundwire. This goes into AUX input of wcd. Wcd codec
outputs analog audio into wsa8815 amplifier. Capturing works through vamacro
using one onboard DMIC which is directly connected to vamacro codec.

Changes since v2:
-- dropped [PATCH v2 08/14] dt-bindings: arm: qcom-soc: extend pattern matching
to support qcom,wsa881x and replaced with new one;
-- dropped [PATCH v2 14/14] ASoC: qcom: sm8250: force single channel via RX_1 output for qrb4210
-- reordered as suggested by Krzysztof;
-- updates to wsa881x-common.h registers descriptions and corresponding updates
to wsa881x-common.c (Konrad);
-- sorted subnodes in DT alphabetically as suggested by Konrad;
-- wsa881x bindings updates (as suggested by Krzysztof);
-- ASoC: dt-bindings: qcom: Add SM6115 LPASS rxmacro and vamacro codecs
is still present;
-- added "qcom,wsa8810" compatible to wsa881x-i2c.c;
-- wsa881x is still present in wsa881x_probe_common();
